TECHNICAL DATA
I. LAMP
The Mighty Arc Series II/S uses a Osram HTI 400w/24 lamp or equivalent. This is a 400
watt high luminous vapor discharge lamp utilizing a short light-arc with exactly adjusted
metal halides in the envelope. It is mounted in an integral pre-focused dichroic reflector.
The arc operates at 55 volts. The lamp current is 7.3 amps. A ballast is used to operate
the lamp from standard 120V, 50/60Hz power. Replacement lamps are available from
Osram lamp distributors as well as from Phoebus Manufacturing.
Lamp life is an average of 250 hours in normal use. The life depends on the burning
time per start. Lamps burned for several hours per start will last longer. Operation for
less than 15 minutes per start is not recommended. An hour meter is mounted on the
housing to keep track of lamp life (or rental usage). Lumen loss occurs typically at end
of life and the lamp will fail to start. Another end of life symptom is arc swirl or flicker in
the projected image.
Occasionally, a new lamp may exhibit this problem. Return such to your Osram distributor for exchange.
Color temperature is about 5600° Kelvin (white) but may vary somewhat from lamp to
lamp.
In handling the lamp, avoid touching the quartz arc tube. Use the outside of the reflector or the porcelain base. If the arc tube is touched, clean it with alcohol or freon before
use to prolong lamp life. There is no hazard in handling the lamp, since high pressure is
present only when the bulb is hot. Due to the small arc chamber, these bulbs present no
explosion hazard in contrast to xenon and other high pressure lamps.
The lamp is cooled by a blower located below the lamp. This blower is essential to lamp
operation. Improper cooling will cause decreased life and arc instability or color shift.
The HTI 400w/24 requires a warm up time of 45 seconds to provide full light output. If
power is interrupted while the lamp is running, the arc will extinguish. Avoid hot re-strike.
This will reduce lamp life. Flip the power switch to middle position and allow lamp to cool
before re-striking.
II. ELECTRICAL
The Mighty Arc Series II/S operates on 105 to 125 Volt 50/60 Hz AC. Present models
draw less that 5 amps, starting or running, at high power factor. An electronic ballast is
used to supply the lamp with proper starting and running voltages and currents.

MAINTENANCE
I. LAMP INSTALLATION
1. Turn Power Switch to Off position and unplug unit from power source.
2. Remove four thumbscrews on rear housing.
3. Lift rear housing up to remove.
4. Unplug lamp connector.
5. Unsnap fiberglass plate from base of lamp. Do not unhook springs.
6. Lift lamp straight up and out of its holder.
7. Position lamp inside ring on lamp plate. (See diagram below for correct lamp positioning). Snap plate over base of lamp. Mount lamp plate back onto three posts.
8. Plug lamp connector in.
9. Plug the Mighty Arc Series II/S in and turn power switch to on (upper position).
Lamp should strike within 20 seconds and warm up within a minute. Set the lenses
for a narrow spot (long throw position). Observe the distribution of the light across
the area illuminated. The brightest point should be in center. If it is off to one side,
remove rear cover and proceed to adjust the 3 lamp adjustment thumbscrews on
the rear of the lamp bracket, one at a time, to center the pattern. WARNING: Do
not look directly at running lamp. These lamps emit dangerous ultra-violet radiation. We recommend wearing clear or tinted safety goggles when making lamp
adjustments.
10. Replace the rear cover. Replace the four thumbscrews.
NOTE: To prevent lamp breakage during long shipments, removal and separate
packing of the lamp is recommended.

III. LENS CLEANING
1. Remove front and rear housing to access all lenses for cleaning.
2. Clean all lenses using glass cleaner and a soft, lint-free cloth.
3. To access all surfaces of the dual front lens system, remove the four bolts from
second lens (not mounted to the lens block). Clean first lenses (front and back).
Clean second lens front and back. Replace with the four bolts.
4. Slide rear lens forward and clean both surfaces.
5. Replace front housing and secure with thumbscrews.
6. Replace rear housing and secure with thumbscrews.
IV. HOUSING REMOVAL AND LUBRICATION
1. Remove rear housing (see lamp change procedure).
2. Unscrew the three control handles on top of unit and remove.
3. Unscrew the thumbscrews on the front housing.
4. Tighten vertical tilt lock knobs on either side of yoke (unit will be unbalanced with
housing off).
5. Grip housing at front and rear top edges.
6. Lift straight up until front lens is cleared, and remove.
7. Wipe all four bearing shafts with a clean cloth dampened with light wax or light
lubrication (WD-40). Avoid excess wax.
8. Operate front and rear lenses forward and back to distribute wax.
9. Replace housing, holding front and rear. Guide over lens and line up front of
housing and bulkhead of chassis.
10. Guide rear of housing down and align with thumbscrew pems on the chassis
rails.
11. Replace thumbscrews.
12. Insert and screw in three control handles.
13. Replace rear housing (see lamp change procedure).

V. TROUBLESHOOTING – LAMP AND BALLAST (ELECTRICAL)
1. If blower fails to run, check power and fuse. Replace fuse with 7 amp 3AB fuses.
2. If blower runs and lamp does not strike.
A. Check that the lamp connector is firmly seated in its socket. If so, the lamp may
have reached the end of its life. Replace the lamp.
B. If the new lamp does not strike, check line voltages. Lamps may not start with
power line below 105 volts.
C. If the above measures have not been successful, the ballast is probably defective. Call your distributor or Phoebus Manufacturing for further assistance.
